Hi

My sump broke and will need to be replaced. The tank is mostly SPS and fish. Its a 300g tank and I have three Tunzes running so lots water movement. How long can I run without the sump and skimmer.

Anything I should l know that I haven't mentioned?

Thanks

As long as you have heat and flow I don't see why you couldn't indefinitely run without one. Just keep up with your water changes and parameters in check.
 
Yea it can be ok but lot more work. As anyone with sps knows some can be finicky while others just dont care just keep up with self cleaning and get a sump lol
 
There are a lot of people who run skimmer less sps tanks. Not saying it's easy but if done right it definitely won't kill him.

on nano tanks that may be fine

but on a 300 gallon tank :) water changes would def kill him before they kill sps haha
 
Most all the SPS corals are of the mini-colony size at the moment. my plans are not to go skimmerless but will be without the skimmer while I find a sump replacement and pipe it all up. I figure it will be two weeks until I get it all back running properly.
 
Only fear is the fear of the unknown as I have always ran a skimmer. That's why I love the feed back on this site......
 
I don't understand all these fears about going skimmerless on an SPS tank. I went skimmerless for months on a 210. The colors and growth got better if anything, especially in Vivid's Rainbow. I only went back to using a skimmer because I got an algae issue, which is now fixed.

I wouldnt worry about the skimmer hell mine stops working for weeks before i even notice it not working i worry more about the filtration and o2 level power heads will keep the water moving but i wonder if he should add a air stone to make up for the sump just a thought

The only thing to fear is fear itself. Run without a skimmer for a few months, watch the parameters, as long as they don't change much, you probably don't even need one.
 
Depends on your bio-load. If I don't run skimmer for 2-3 days I start seeing algae, cyano....etc

Like others have said, just watch your params and adjust accordingly.

Yep I agree from what I have seen people see great growth and color while they stop using skimmers.
 
On my old setup, I dint use a skimmer heck I was even using a canister filter .... and honestly that was the best setup I ever had...40B doing 5 gal water changes a week. I miss the simplicity of that tank.
